Question

Find the length of AB?

Answer 1

AB ≈ 4.09

Explanation:

Using the sine ratio in the right triangle

sin17° =
`(opposite)/(hypotenuse)` =
`(AB)/(BC)` =
`(AB)/(14)` ( multiply both sides by 14 )

14 × sin17° = AB , then

AB ≈ 4.09 ( to 2 dec. places )

Answer 2

Choice 3) AB = 4.09

Explanation:

sin 17° = AB/14

0.2924 = AB/14

AB = 4.09
